It has been confirmed that realm of Chaos will be the center of one of the two Expansions to TW: Warhammer. Thoughts on this? As a person who doesn't know much about the Warhammer races and units, I'm afraid that the 4 main factions of the expansion (Nurgle, Tzeentch, Khorne, Slaanesh) will be very similar with only different lords, campaign mechanics and slight roster differences like Greenskin/Bloody Handz/Crooked moon.
